' Application filed April 27,1910. Serial No. 558,031.

To all whom it may concern:

Be it known that I, JOHN HANsEN, a resident of Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Gar-Door-Opera'ting Mechanism; and I do the following, to be a full,

My, invention relates to car door operating mechanism, and isespecially adapted for combined freight and dump cars, though it is adapted for use with any suitable kind of car doors. Its object is to provide a -sim ple form of operating mechanism by which lifting mechanism to hold the door in closed position and the supporting means so pro-' vided are automatically thrown out of engagement in the turning of the operating shaft in the opposite direction.

It consists, generally stated,.in combining with a car body hav'n a support thereon, a hinged door, a rotata lile shaft for raising the .door to closed position, and a hook carried by the door and adapted when the door is raised to engage with the support on the car bodyto hold the door closed; to:

gether with. means on .the rotating shaft adapted to engage with the hook and draw it'away from the support when the door is tobe lowered.

It also consists of other improvements as hereinafter set forth.

'In the accompanying drawing Figure 1 is a side view of a car embodying the invention; Fig.2 is a cross section. thereof; Fig. 3 is an enlarged. side View of the car door operating mechanism; Figs. 4 and 5 are enlarged cross sections showing the locking mechanism in different positions; 6 and 7 are perspective views of the locking hook and support respectively, and Fig, 8 is a de tail view of a modification.

The invention is illustrated in connection. with a combined freight anddump car, that is, a car-having a snbstantially'flat floor and vertical sides, and with doors swinging out to the side It is also shown in connection with the car body forming the sol ject matter of a companion application of evcxidate herewith, Serial No. 558,032, in which the pocket for the rotating shaft is formed by beni ling the bottom portion of the. plate forming the car side inwardly from the cortical stiffener or stake and again outwardly to the same, forming an exposed from blows from passing from the side oftheicar.

automatically taken from the pocket on the outside 0. the car in which the door closing,;mecha nism is protected trains and the like by means of the side sta i as, thus giving free access to the door ops rating mechanism The car door op erating mechanism form ing the subject of this application is speciaily adapted for use within such pocket and till he described in connection with the same, though it can of course be employed in cc nnection with any car door and may be supported in any suit V able way.-v

The car body as illustr: ited has the center sills 1, the bolsters 2, tr msoms-3, the car sides 4, as well as the ott er elements neces-' sary to form. the car body.- The car sides 4 as illustrated are of plate girder form, having the side plates 6 and vertical stifieners or stakes 5 and the usual top chords 7. To form a pocket for the rece ation of the winding shaft and to form the bottom chord of the plate girder side the b ittom'of the plate 6 is bent inwardly at a. do vnward incline as at 8 and then again beni outwardly-pref erably at a downward in :line as at 9, the base of the plate being bent downwardly in line with the upperpart oi the plate as at 10, thus forming a triang ii pocket ll-to receive the chain shaft 15. The base portic-n of the plate thus forms the bot tom chord of the plate girder side and as riveted to the side stake 5 above and belovthe pocket gives very st-I ongconstruction, while providing the pocket 11 on, the out side of the car body where the lifting and locking mechanism' is ex; osed on the ear side, giving easy access the 'eto. In erecting the car the bolsters or t-ra1 isoms 2 or 3 are provided with suitable ang les or flanges 13.

to be riveted both to the lower inc-line 9 and the lower vertical flange 10 of the side plate and to the base of the stifi ener asindi-- (rated. Suitable transverst floor plates 1d extend over the tops of ihe bolsters and transoms, and are connected to thewalls of the triangular pockets such: as by the up:

turned flange 15 riveted to he inclined wall The doors 16 are shown as hin ed to the center sills and are illustratei'l as i ormed of flanged plates fitting into thi pockets formed ice for their reception in the (penings formed 7 in the floor. dooi' it is inclined-as at 17 inclined-wall i) of the pocket.

The Winding shaft 12 is nonnted within- At the forwa id edge of each lo'fit against the the triangular pocket 11 in any suitable way,

such as'by brackets 18 riveted to the stakes 5, and it may have any suitable connectidn with the door for'lifting the same to closed position. I have illustrated the chains 19 secured to theshaft and extendin down through openings 20 in the incline wall 9 of the car side and engaging with brackets 21 riveted to the outer edge of the door.-' 'As illustratedin'the drawing I prefer these chains to connect to eye-bolts 22 which are secured to the hooks 23, said hooks being pivotally connected at 24 to the brackets 21. An suitable connection'between the door and winding shaft may. of,course be employed. Thepreferred shape of these hooks 23 is illustrated in Fig. 6, the hook having the bearings 25 and above the same the side lug 26 in which the eye-bolt 22 is secured the car according to the forming the exposed pocket 11; and it has the bearings 30 to'support the cross bar or lug-29 extending between saidbearings and forming the door support. Secured upon the winding-shaft in line with each hook 23 is' the knocker 31 carryingfa lug 32 which engages with a shoulder 33 upon the book 23'. Said knocker is located in such position that when the shaft is rotated in the direction to release the doors its lug 32 will contact with the shoulder 33 and so draw the hook away from the supporting bar 29and release the hook from engagement therewith. The operating shafts can be'niade of any desired length and may extend toward or to the end of number of doors formed in the car bottom,

- ;In the use of the invention, when the door 2,-and it is desired to close the door, the

shaft 12 is rotated to wind up the chain such as in the direction of the arrow in Fig. 4, and, when the door is brought into position for closing, the book 23 passes through the opening 20 in the bottom wall 9- and. its upper inclined face 34 contacts with the supporting bar or lug-29 and isforced outwardly as the shaft is turncduhtil the hook projection 27 asses said bar, when it snaps back over t 'e bar and catches thereon as illustrated in Fig. 4 and to the left in Fig. 2, thus lockingthe door' in closed position and supporting it upon the and may be op-- erated by any suitable mechanism, which' it is not considered necessary to illustrate;- 50 w is open, as illustrated to the right of Fig.

body and relieving thewinding shaft of the entire load thereon. .The drawing shows two such hooks for each door a1 d this is:

the preferred construction. In order 'to open the door the shaft 12 is rotated in the opposite direction as indicated by the arrow in Fig. 5, and in the first turn thereof the lug 32 of the knocker 31 strikes againstthe shoulder 33 of the hook and draws it out wardly away from the supporting bar or lug 29 and so frees the hook from its suprt and leaves the door free to swing d wnwardly. v

As the" invention is preferably employed with a car of the construction shown in the drawing it will be'seen that when the door is held closed, as the support 28 is about .in.line with the top of the door a short positive support close to the meeting faces of the door and car body is provided, and the inclined face 17 of the door is held in close contact with the bottom inclined wall 9 of the pocket 11, so practically sealing the joint between'tthe door and car body.. In closing the door the line ofstrain fromthe bracket 21- to the winding shaft 12 is directly throughthe body of the hook 23 and in such line as will normally hold the hook in engagem'entwith the supporting bar or lu'g, while the' lower face of the hook may be slightly inclined to hold the book in engagement with said' lug;

though the locking of the chain shaft would prevent the-outward movement of the hook necessary to disengage it until the chain is loosened and some posltive means such as 'the lug on the knocker is employed to disengage the hook.

Fig. 8 shows a modification inwhich the bottom chord 35 isiformed with the inclined portion 36, and the bottom portion 37 first bent outwardly on a horizontal plane instead of inclined as in the other figures, and 4 then downwardly as at 38 and riveted to the stake and cross member. Otherwise it is the same as'in the other figures.

'The apparatus is simple in construction and as the hook is itself part of the lifting mechanism th eonlyadditions necessary overv the ordinary chain winding device is the hook projection and the support with which it engages on the carbody, an-extremely simple car door supporting mechanism be ing thus provided.
